(Reuters) - China's Wang Kaihua produced the third-fastest 20 km race walk in history at the national championships in Huangshan on Saturday, romping to victory in one hour, 16 minutes and 54 seconds to book his spot at the Tokyo Olympics.
The Asian Games champion paced himself perfectly from start to finish at the event, which also served as an Olympic qualifier, taking 42 seconds off the national record previously held by 2016 Rio Games champion Wang Zhen.
